This invention relates to headlights and more particularly to headlights designed for automobiles, an object of the invention being to provide an improved shape andcon-j struction of reflector and lens which w1ll give full road illumination but will prevent glare.

of this character in which the lens projects 14) forwardly from the reflector so as to, give lateral illumination and also to permit the headlight to be observed by cars approach ing at an angle thereto.

A further object is to provide a headlight 15 of this character which will be of simple and inexpensive construction, strong and du-. rable in use, and. which will most efliciently perform the functions for which it is in-' tended. With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and claim.

In the accompanying drawings- Figure 1 is a view in longitudinal section, illustrating myimproved headlight; Figure 2 is a view in horizontal section on pointed out in the I 80 the line 2--2 of Figure 1;

as shown in Figure 1. The lower half of the reflector at the rear thereof is of general concave shape forming in effect a depression 1, and a lamp 2is located in a socket 3 at the rear of the reflecto1 and positioned properly with relation to the-several reflecting surfaces to perform the functions more fully hereinafter pointed out.

The front wall of the depression 1, constituting the concave reflector, merges into a horizontal flat surface t located slightly below the vertical centre of the headlight.

At the forward edge of the portion 4 a. downwardly and forwardly inclined flat surface 5 is rovided ,which merges into the transas verse 31 circular wallof the reflector. This constitute a Wall or bridge, indicated at 8,

surface 5 is preferably dulled in any approved manner so that it is not a full or direct reflector of light. The forwardend ofthe reflector has string 6 secured thereto and this ring supports the lens B.

I would call particular attention to the r v shape of this lens B, which is of general cy- A further object is to provide a headlight lindrical form projecting forwardly an appreciable distance and having a convexly closed forward end 6. The upper half of this lensB is frosted or otherwise rendered translucent, as shown at 7, while the lower half is clear, as indicated at 9. I

The meeting edges of the concave reflector 1 and the inclinednon-reflecting surface 5 which is in a plane sufliciently high to prevent any direct rays of the light from the lamp 2 from passing through the clear portion 9 of the lens. In other words, the rays of light are prevented from forming a horizontal bolt of light but are all directed downwardly by reason of the several refleeting surfaces above described. Hence, the downwardly directed rays through the lower clear portion 9 of the lens give a full road illumination, and the frosted upper surface of the lens, combined with the fact that none of the rays of "light are inclined upwardly,

prevents any possibility of glare.

Furthermore, the inclined dulled surface 5 of the reflector gives to the headlight the general appearance of having a completely dulled or translucent surface. In other words,the optical effect when a person looks directly into 'the lens is that he sees the translucent portion 7 in the upper portion of the lens and the dulled surface .5 gives him the impression that the whole front of the lens is translucent.

Byreason of the fact that the lens is projected forward an appreciable distance, lateral illumination is hadand also automo biles approaching at an angle can see the headlights and accidents will be prevented.

I do not wish to be limited to the exact material, shape, size and proportions of my improved headlight but desire to cover the general arrangement, and hence various slight changes and alterations might be made in the general form of the parts described withoutdeparting from my invention and therefore I do not limit myself to the precise details set forth but consider myself at liberty to. make. such slight changes and no /alt erations as fairly fall within the spirit horizontal flat surface'at its forward ed e, 10 Y and scope of the appended claim. and said reflector at the forward edge of t e I c aim':- flat surface having a forwardly and down; A headlight, comprising a reflector, the wardly inclined dulled portion, and a for- 5 upper half of which is parabolic in horizonwardly projecting lens secured to the front tal section and semi-parabolic in vertical of the reflector and translucent throughout 15 section, the lower portion of the reflector at the upper portion thereof.
